Summary: This study compared the cellulase lignin structures in normal and tension wood of Poplar 107, and found that tension wood had higher lignin content. Both normal and tension wood were dominated by syringyl units, with tension wood showing higher content of certain elements compared to normal wood.

Summary: Wood formation in trees is a complex process that involves protein-protein and protein-DNA interactions. In this study, we developed a high-throughput screening system to detect these interactions in wood development. Multiple regulatory modules of lignin biosynthesis were identified, and some interactions were further validated.

Summary: In this study, lignocellulose materials obtained from ozone treatment of aspen wood were analyzed using various spectroscopic techniques. The results showed that ozone was most effective in destroying lignin within a specific range of ozone consumption, and the destruction of lignin was associated with an increase in fluorescence intensity.

Summary: Abundant studies have shown that single-walled carbon nanotubes (SWCNTs) have positive effects on poplar growth. SWCNTs were absorbed by poplar root cells and resulted in increased plant height, leaf size, and fresh and dry weight. The stems of SWCNTs-treated poplar had higher cellulose and lignin content, as well as elevated enzyme activity and gene expression related to cellulose and lignin synthesis. The findings suggest that SWCNTs can enhance poplar wood formation by modifying the expression of enzymes involved in cellulose and lignin synthesis pathways.

Summary: This study investigated the mechanisms of rubber tree lignin biosynthesis by analyzing transcriptome changes in different types of wood. The results suggest that hormone signal transduction and phenylpropanoid biosynthesis pathways may play crucial roles in reaction wood formation. Additionally, a TF-gene regulatory network was constructed, revealing MYB, C2H2, and NAC TFs as potential regulators of phenylpropanoid biosynthesis in rubber trees.

Summary: Wood is a crucial carbon reservoir in the biosphere, composed of large polymers and soluble extractives. Molecular interactions within wood are not fully understood. By expressing a fungal alpha-glucuronidase in the wood cell wall, the role of 4-O-methyl glucuronopyranose acid (mGlcA) in wood composition was investigated. The results challenge previous understanding of wood cell wall composition and reveal a novel function of mGlcA in binding suberin-like compounds to the cell wall.

Summary: An association genetics approach was used to investigate the genetic control of wood traits in European black poplar. The study identified several candidate genes and their associations with cellulose, lignin, and 6C sugar contents. Moderate heritabilities were observed for cellulose and 6C sugar, while lignin had low heritability. Single-marker associations were found for cellulose, lignin, and 6C sugar contents, with one marker (CesA3A-15-456) showing a significant association with cellulose. Further investigation with a larger and diverse study population is warranted for these associations.

Summary: DCG, a phenylpropanoid-derived plant metabolite, is claimed to have cytokinin-substituting and cell-division-promoting activities. However, our experiments showed no morphological changes or transcriptional shifts in Arabidopsis seedlings, indicating that DCG does not have the reported activities. Furthermore, no evidence was found to support the uptake of DCG by plant cells, explaining the lack of observable activity. Despite an increase in DCG content in plant tissue, there was no demonstrated activity for this metabolite. These findings call for a reevaluation of the attributed cytokinin-substituting and cell-division-promoting activities of DCG.

Summary: Understanding the impact of maturation stress and wood properties on poplar tension wood is crucial for maximizing lumber yields. This study analyzed the longitudinal maturation strains, physical and mechanical properties, and cell wall nano-mechanical properties of artificially inclined poplar trees. The results showed that inclination had mixed effects on wood quality, with higher RLMS and certain properties on the upper sides of inclined stems. However, other wood properties fluctuated or changed little with height. The RLMS proved to be reliable indicators of wood properties in the tension wood area and at specific heights.

Summary: Leaning stems of woody plants form reaction wood called tension wood (TW), which has special fiber structure. Xyloglucan endotransglycosylases (XETs) play a key role in cell wall modifications in TW, and the colorimetric assay can be used for fast detection of TW presence.

Summary: This review presents the regulation of the phenylpropanoid pathway by MYB transcription factors, which activate downstream structural genes via Phospholipase D/phosphatidic acid signaling, leading to developmental and/or stress responses. Specific MYB transcription factors influencing the biosynthesis of anthocyanin, flavonoid and lignin are discussed, as well as their roles in activating biotic and abiotic stress responses.

Summary: Tension wood (TW) is a specialized xylem tissue formed in response to mechanical stress in angiosperm trees. The development of TW involves the regulation of secondary cell wall genes, leading to altered wood properties. Through analysis of TF-DNA interactions and gene editing, this study identified key transcription factors involved in the regulation of wood composition under tension stress, providing insights into the coordinated regulation of metabolism, growth, and stress adaptation in trees.

Summary: The study demonstrated that using rare sugar-based products can induce resistance in grapevine leaves against downy mildew, primarily through enhancing the activation of salicylic acid- and jasmonic acid/ethylene-responsive genes and stilbene phytoalexin accumulation. IFP48 provides protection against P. viticola infection, but shows inconsistent effects against B. cinerea.

Summary: This study evaluated the radiosensitizing potential of Au@DTDTPA(Gd) nanoparticles combined with conventional external X-ray irradiation (RT) for treating GBM. Various biological models were used to investigate the impact of RT combined with Au@DTDTPA(Gd) nanoparticles on tumor progression. Results showed that the combination therapy reduced tumor invasion and decreased the number, viability, and aggressiveness of escaped tumor cells, thus reducing the risk of recurrence.

Summary: Grapevine trunk diseases (GTDs) cause significant economic losses in wine-producing countries. Researchers conducted nursery experiments using Trichoderma atroviride (Ta) SC1 and Bacillus subtilis (Bs) PTA-271, alone and in combination, to study their biocontrol effect on GTD pathogens. The results showed that these biological treatments reduced the infection rate and fungal isolation of GTD pathogens in grapevine nursery material.
